A protector sleeve assembly for a balloon catheter, configured for being removably disposed on at least a section of the catheter and preferably on at least the catheter non-inflated balloon prior to introduction of the catheter in a patient's lumen, including a radially collapsible inner sleeve, and an outer sleeve with a tapered section. The inner sleeve has a relaxed configuration with an inner diameter greater than the outer diameter of the noninflated balloon, and a collapsed configuration with an inner diameter less than the relaxed inner diameter. The outer sleeve is slidably positioned on at least a portion of the inner sleeve and has a tapered first section with an inner diameter tapering towards a nontapered second section, the nontapered second section having a substantially uniform inner diameter less than an outer diameter of the relaxed inner sleeve and configured to hold the inner sleeve in the collapsed configuration.
